SEAPLANE BASES AND
OUTSTANDING TOOL OF THE CONCRETE CONSTRUCTION INDUSTRY!
UMPCRETE, America's only concrete pump, has come of age!
Rapidly since its introduction in 1932 — and at an accelerated
pace during the past few years — the cost-cutting abilities of the
Rex Pumpcrete and its pipe line have become identified with more
and more concrete structures of all sizes and all classifications,
men throughout the construction industry, Pumpcrete has become a
standard tool, to be used consistently on job after job; to be looked
upon as a factor which means savings in cost and time and which
will permit speeding up all other operations on the job with a con-
sequent reduction in overhead.
The reasons for Pumpcrete's remarkable record of pumping millions
of yards of concrete in a few years are simple. Pumpcrete takes con-
crete placing out of the "lift-and-carry" category and makes it a
simple pump and pipe-line proposition.
It saves time and money formerly spent in erecting and operating
buggy-runs, chutes, hoists, towers, and other old-fashioned equipment.
It simplifies difficult jobs.
It permits a more orderly, economical job progress.
It is a direct link between mixing unit and forms — often eliminating
It does all this — and it does it consistently on jobs ranging in type
and size from the Navy's largest dry docks to the simplest culvert or

Every once in a while there appears a machine that
"clicks" right from the start— that moves into the aver-
age contracting setup and starts performing mechani-
cally and from the cost and profit standpoint in a way
that immediately shows its superiority over machines
and methods previously used.
That's the case of the Rex Pumpcrete. While this con-
crete pump is not the answer to every concrete plac-
ing problem, it offers so many fundamental advantages
for such a wide variety of concrete construction work
that it has been accepted as a standard tool of the
industry — a low-cost method of placing concrete on
concrete jobs all over the country.

HERE'S HOW IT PUMPS
Inlet valve between hopper and chamber
is opened to allow charge of concrete to be
drawn into the cylinder by suction of the
piston. At this time, the outlet valve is
Outlet valve is opened, and with inlet
valve closed, piston forces charge of con-
crete through outlet passage. Valves, which
are called "plug cocks,'' are opened and
closed in timed relationship to the move-
ments of the piston.

3-WAY SELECTIVE DRIVE FOR DOUBLE PUMPCRETES!
Rex Double Pumpcretes operate on the same principles as the
Single Pumpcrete described above, except that they have two
pumping cylinders instead of one. They are equipped with the
Rex 3-Way Selective Drive transmission which enables the opera-
tor to pump through both cylinders simultaneously to gain full
pumping capacity or to shut down either side of the pump without
interfering with the continuous flow of concrete from the other
cylinder. Because of this, the 3-Way Selective Drive effectively
answers the requirement of standby equipment contained in the
specifications on many important jobs. On pours where two points
are being placed simultaneously, the 3-Way Selective Drive
enables the operator to slow up the flow of concrete in either pipe
line to regulate the rate of pour — this is often a necessary process,
as on the overbreak in tunnels. On other types of jobs where two
mixes are used, the selective drive enables them to be pumped
through separate pipe lines at the same time, merely by using a
simple partition in the hopper. You get three Pumpcretes in one
with this new 1941 Pumpcrete feature!
This drawing shows how the 3-Way Selective Drive
gives you three Pumpcretes in one.
PIPE LINE !
Not the least of Pumpcrete's many unique features is its easily handled
pipe line! Pipe line comes in a variety of convenient lengths shown
on page 23) which enable you to reach any point on the job from the
Pumpcrete setup— and to have enough additional pipe ior the most
economical job progress. Once your Pumpcrete is spotted, pipe line
is laid from Pumpcrete to final delivery point and pipe sections are
qu ly coupled or uncoupled with the simple "toggle" couplings
illustrated above. No bolts or wrenches are required. Coupling or
uncoupling the Rex pipe line requires but a few seconds for each
connection, and you can uncouple the pipe without interfering with
the flow of concrete. The Rex toggle coupling is positive and fool-
proof and gives the connected pipe line the required rigidity without
further lateral bracing.

HOW TO FIGURE
LINE FOR YOUR JOB...
The following table of Pipeline Data is based on con-
verting the pumping resistance of any combination of
straight pipe, bends and differences in elevation to the
resistance of an equivalent length of straight horizontal

**Not over 200 ft. of pipe actually. A combination of horizontal and ver-
tical distances is to be calculated on the basis of I ft. of vertical equal-
ing 8 ft. of horizontal pumping. The total equivalent distance should
not exceed the equivalent horizontal pumping distances shown in the

crete, Model No. 200, pumping through 8" O. D. pipe-
The total actual length of pipe line is 360 feet, which is
made up of the following sections:
320 ft. straight pipe
There is a vertical lift at the end of the pipe line of 40 ft.
The equivalent length of straight horizontal pipe is
determined as follows:
320 ft. straight pipe Equals 320 ft.
2—90 bends (Equivalent to 40 ft. straight
pipe) 80 ft.
4 — 45 bends (Equivalent to 20 ft. straight
pipe) 80 ft.
40 ft. vertical lift (Equivalent 1 ft. vertical
equals 8 ft. horizontal) 320 ft.
The following straight line curves are pre-
sented so the contractor may better judge the
amount of concrete in the pipe line. The in-
formation is of great value in holding con-
crete losses to a minimum when nearing
the end of a pour.
The quantity of water required to clean out
the pipe line with the Go-Devil may be com-
puted from the above table by converting
cubic yards of concrete into gallons of water.

The picture at the left shows the pipe
line set-up for pouring 5.000 yards of
concrete in the roof and floor construc-
tion (an area of 225,000 sq. ft.) on the
Brooklyn High School for Homemaking.
Concrete for dozens of other buildings,
warehouses, steel mills, plants large
and small, containing anywhere from
1,000 to more than 100,000 yards, has
been pumped in place by the Pump-
crete. Doesn't this show adaptability and
wide range usefulness? You'll know
how true this is when you figure plac-
ing costs in your building work. Com-
pare Pumpcrete costs against those of
any other placing method. The chances
are 10 to 1 that you'll find you can do
it cheaper with the Rex Pumpcrete.

As a unit for transporting and placing
concrete in tunnels the Rex Pumpcrete
has a performance record that no other
method can approach for fast, efficient,
low-cost placement of high quality con-
crete. Pumpcretes have placed millions
of yards of concrete in the rock tunnels
of the famous Colorado River Aqueduc*;
in the muck tunnels of Chicago and
Detroit; in the treacherous ground under
New York City and many other local-
ities. Pumpcrete's background includes
dozens of other tunnel jobs ranging
from the world's largest tunnel, the
Yerba Buena Tunnel in San Francisco
down to a 4 l 2 foot tunnel in Gary. At
the right is a photo of the Rex 200

the new Chicago Subway. This all-
around ability on all types of tunnel
jobs means something to you if you are
after tunnel contracts — it means that
Rex Pumpcrete is a tried, proved method

OVERPASSES AND UNDERPASSES
The Rex Pumpcrete has shown remark-
able success in placing concrete for
structures in this class of work — from
the large jobs over 10,000 yards down
to the small 500 yard overpass or under-
pass. The photo at the left shows the
set-up used for the 10,000 yard West
Lancaster Street Overpass job in Fort
Worth. Texas. The Rex 160 Pumpcrete
used on this job was charged by Moto-
Mixers and pumped approximately 55
cubic yards in the pedestals and caps of
each pier with new speed and economy.
To this class of work, Rex Pumpcrete
brings many time-saving, money-saving
advantages which should be working
for you. Before you bid another over
pass or underpass job, get all the facts
and figures on Rex Pumpcrete's per-
formance. You'll see why you can't go
wrong with Pumpcrete!
Pumpcretes have cut placing costs on
dozens of lock and dam jobs! This in
eludes over 14 Mississippi River lock
and dam jobs where Pumpcretes pump
ed and placed over a million cubic
yards! Pumpcretes placed approxi
mately 275,000 cu. yds. of concrete in
the world famous Boulder Dam! Pump
cretes have placed hundreds of thou
sands of yards of concrete on all sizes 1
and types of hydro-electric dams, spill
ways, earthen dams, flood control pro
jects, etc., from Bonneville, Oregon, tc
Seboomook, Maine. The Rex 160 Pump
crete with its capacity of 15 to 20 cu
yds. per hour has set an enviable
record on smaller jobs of this kind
Such a background of successful per
formance is ample evidence that Pump
crete is thoroughly adaptable to this
class of work — evidence that yoi
should bid with this advantage rathei
than against it!
BID SEWAGE AND WATER TREATMENT PLANTS OR RESERVOIRS
ige s, filtration plants and
with combinations of slabs,
am and columns placed over
ipaiatively wide area are ideal
npciete jobs. Rex Pumpcretes have
laced concrete on this type of work in
practically all parts of the U. S. A. This
includes job6 as small as a 1.500 yard
sewage treatment plant at Two Rivers,
Wisconsin, 50,000 yard jobs in Milwau-
kee and Detroit, and the 200.000 yard
ago Filtration Plant. Shown here is
the Jamaica, Long Island, New York
Sewage Disposal Plant in which a dou-
ble Pumpcrete placed 35.000 cubic
yards into circular tanks of 80 and 120
foot diameters. The pipeline set-up was
made for continuous pouring at a rate
of 50 cubic yards per hour.
Marine work of all kinds including
causeways, breakwaters, jetties, dry-
docks, caissons, sea coast defenses, etc..
is still another class of concrete con-
struction where the Rex Pumpcrete has
gained wide favor through its simplicity
and easy adaptation to all types of job
At right is shown a Rex Pumpcrete
which is pumping concrete for a long
jetty on the shore of Lake Michigan,
with pipe line extending far out into the
lake. This ability to transport concrete
from mixing unit to distant form work is
the Pumpcrete's and the Pumpcrete's
alone. No other concrete placing meth-
od offers this inherent advantage. If
you bid this class of work, Pumpcrete is
probably the cost-saving answer.
IF YOU RID UNUSUAL OR INACCESSIBLE I0BS
Many concrete construction jobs offer
problems that make them inaccessible
by ordinary concrete placing methods.
It is important to note that many jobs
which ordinarily could only be placed
at prohibitively high costs, become or-
dinary, simple jobs when the Rex Pump-
crete is brought into action. For in-
stance, the Rex Pumpcretes have placed
concrete in such difficult spots as tur-
bine chamber linings and power house
underp innings: Pumpcrete has placed
the concrete for track elevations and
tunnel linings without interfering with
the flow of traffic. This last is shown in
the picture at the left. Here the Rex
Pumpcrete is pumping concrete for tun-
nel lining without even the slightest in-
terruption of regular railroad traffic.
Before you bid complicated, inaccess-
ible types of jobs, see how easy and
profitable they can be when placed
with the Rex Pumpcrete and pipe line.
WHAT IS THE REX PUMPCRETE?
The Rex Pumpcrete is a pump that pumps concrete through a pipe line. It is a rugged
horizontal piston pump with large size mechanically operated outlet and inlet valves.
Concrete from a hopper above the valve chamber is drawn into the cylinder on a suction
stroke and expelled into the pipe line on a pressure stroke. The pipe line is completely
filled and there is a continual flow of concrete from the end of the line.
HOW HIGH AND HOW FAR WILL
IT PUMP CONCRETE?
The distance concrete can be pumped is dependent on the diameter of the pipe, the
number of elbows required in the line, and the elevation of discharge above the Pump-
crete. Generally speaking, the Rex 160 Pumpcrete can pump concrete a horizontal dis-
tance of 800 feet, or a vertical height of 100 feet. Larger Pumpcretes are capable of
pumping as high as 120 feet or as far as 1200 feet — and even farther with plastic con-
crete. Any combination of horizontal and vertical pumping within these limits can be
handled very efficiently, thus enabling you to place concrete from one set-up to all
points within its range.
WHAT IS ITS CAPACITY?
The Rex 160 Pumpcrete has a capacity of 15 to 20 cubic yards per hour — ideal for work-
ing with 10-S or 14-S Mixers, Pavers or ready-mixed concrete delivery. Other sizes of
Rex Pumpcretes have capacities up to 65 cubic yards per hour. Under normal set-up
conditions and with good average concrete, the Rex 160 Pumpcrete will usually average
better than 15 cubic yards per hour with the other sizes of Pumpcretes offering corre-
spondingly higher averages.
WILL IT HANDLE ALL MIXES?
With a 6 inch pipe line, nearly all commonly used mixes can be pumped by the Rex 160
Pumpcrete, provided they are of a workable consistency with a maximum aggregate size
not larger than 2 inches. The larger Pumpcretes with larger diameter pipe lines are
capable of pumping mixtures containing maximum aggregate sizes up to 3 inches.
Practically all mixes ordinarily used on average concrete placement jobs can be easily
and efficiently pumped by Rex Pumpcretes.
WHAT ABOUT OPERATING COSTS?
The operating costs of the Rex Pumpcrete involve the cost of power (either gasoline or
electric where available), the cost of lubrication and the cost of the operator. Ordinarily
power, grease, and oil will rarely exceed 2c per cubic yard. It must be borne in mind that
the cost of the operator depends upon the prevailing wage scale in your locality.
WHAT ABOUT MAINTENANCE COSTS?
Considering the fact that concrete is extremely abrasive, the maintenance cost of wear-
ing parts of the Pumpcrete is surprisingly low. Easily replaceable wearing parts that
come in contact with the concrete are made of special wear-resistant alloy steel. Wearing
parts ordinarily have a working life of from 4,000 to 10,000 yards before replacement is
necessary; and in pumping the first 3,000 to 5,000 yards, the maintenance cost per
cubic yard of wearing parts is practically nothing. The maintenance cost of replace-
ment parts per cubic yard is no more at 50,000 yards of life than at 10,000 yards of life.
WHAT ABOUT PIPE HANDLING COSTS?
Due to the quick-acting couplings on the pipe, the puddling crew, or others in the com-
mon labor class, generally handle the pipe line, especially with the 160 Pumpcrete.
Pipeline costs are difficult to segregate from the puddling costs. However, Pumpcrete
owners have reported pipe handling costs from 2c per cubic yard on 24 inch slabs, to
10c per cubic yard on 6 inch slabs and up to 12c per cubic yard on high, fairly thin
walls. Accurate pipe handling costs can best be estimated after job requirements and
distribution methods are known.
WHAT'S YOUR QUESTION?
A job like yours has been pumped by Pumpcrete! Whatever question you might have
regarding the use of the Pumpcrete on any particular job, Rex can answer it. We have
answered the same question for others in our experience of pumping millions of cubic
yards of concrete on every conceivable type and size of job. Rex Pumpcretes have
placed concrete on bridges, viaducts, buildings, housing projects, tunnels, overpasses,
underpasses, filtration plants, reservoirs, locks and dams, culverts, warehouses, etc. This
is a record of experience that guarantees the correct solution to your pumping problem.
